Description

pShuttle2 is a cloning vector designed for use with the Adeno-X™ Expression System

(Cat. No. 631513; 631022). In the Adeno-X System, standard ligation techniques are used to

transfer a gene-specific expression cassette from pShuttle2 to a replication-deficient, Ad5 genome

(2). The pShuttle2 expression cassette consists of the human cytomegalovirus immediate early

promoter (P­CMV IE), a multiple cloning site (MCS), and the SV40 polyadenylation signal (SV40 poly

A). The entire cassette is flanked by unique I-Ceu I and PI-Sce I restriction sites so that it can be

excised and directly ligated to Adeno-X Viral DNA—the adenoviral genome. The vector backbone

also contains the pUC origin (pUC ori) and a kanamycin resistance gene (Kanr) for propagation and

selection in E. coli.

Use

Insert your full-length cDNA into the MCS of pShuttle2 using any of the unique restriction sites shown.

Your cDNA insert must contain a start codon for proper promoter driven expression in mammalian

cells. After the gene of interest has been cloned into pShuttle2, excise the expression cassette by

digesting the plasmid with I-Ceu I and PI-Sce I according to the one-step double digestion procedure

in the Adeno-X Expression System User Manual (PT3414-1). Because the termini of the excised

expression cassette fragment are compatible with the cloning site in Adeno-X Viral DNA, the cassette

can be directly ligated to Adeno-X DNA to form a recombinant adenoviral vector.
